First Periods: A Guide for Parents of Teens
The menstrual cycle is a fundamental marker of the female reproductive system, and establishing a healthy understanding of it during adolescence is essential. In an interview with Labebe, gynecologist-endocrinologist and reproductive medicine specialist Nato Shengelia highlights that parents’ awareness plays a decisive role in shaping how adolescents experience bodily changes, their psychological readiness for them, and the hygiene habits they form.
Menarche—the first menstrual period—is currently considered physiologically normal at around 10–11 years of age according to modern medical standards. While the typical range was previously defined as 11–13 years, today the lower boundary has shifted to 10. Nato Shengelia also explains that the onset of menstruation before the age of 10 may indicate precocious puberty, whereas the absence of menarche by age 15 is classified as delayed development. Both situations require medical evaluation, as early puberty can accelerate the closure of growth plates and ultimately limit final height potential.
Menstrual Cycle Phases and Hormonal Regulation
A clearer understanding of the menstrual cycle comes from looking at its distinct phases, which unfold as a coordinated sequence of hormonal changes. The cycle is typically divided into four stages: menstrual, follicular, ovulatory, and luteal. It begins with the menstrual phase, marked by the first day of bleeding. During this time, the endometrium—the inner lining of the uterus—is shed and expelled from the body. This is followed by the follicular phase, when ovarian follicles develop and mature under the regulation of hormones produced by the pituitary gland.
Mid-cycle, ovulation takes place. In this phase, a mature egg is released from the ovary and becomes available for fertilization. The cycle then enters the luteal phase, during which progesterone prepares the body for a potential pregnancy. If conception does not occur, hormone levels decline, triggering the start of a new menstrual cycle.
Symptoms and Warning Signs
Menstrual symptoms can vary significantly from one woman to another. The most frequently reported include cramping or dull pain in the lower abdomen, discomfort in the lower back, increased breast sensitivity, emotional fluctuations, irritability, and a general sense of fatigue. Mild symptoms are typically considered a normal part of the cycle, but certain signs should not be ignored.
Concerning indicators include unusually heavy menstrual bleeding, periods lasting longer than seven days, intense pain that does not respond to medication, and irregular cycle lengths—specifically when the interval is shorter than 21 days or exceeds 35 days. Such changes in menstrual patterns can often be an early signal of underlying endocrine or systemic health issues, making medical evaluation important when they occur.
Regular medical Checkups
To support long-term reproductive health, gynecologist-endocrinologist Nato Shengelia, in line with modern medical guidelines, stresses the importance of regular preventive consultations. Medical visits should not be limited to situations when symptoms appear—routine examinations once a year, or as advised by a specialist, help identify hormonal imbalances, inflammatory processes, and other physiological changes at an early stage.
Even when there is a family history—such as a mother experiencing late menarche—it should not be used as a basis for assumptions. Today, adolescent development is strongly influenced by external factors, including nutrition, stress levels, and environmental conditions. For this reason, only consistent specialist monitoring and professional evaluation can provide an accurate and reliable understanding of reproductive health over time.
Recommendations for Parents – Key Priorities
- Monitoring changes – If a teenager experiences intense pain, unusually heavy bleeding, or persistent menstrual irregularities (even after two years of established cycles), consultation with a reproductive health specialist is necessary;
- Hygiene education – Teenagers should be introduced to proper intimate hygiene practices early on. A lack of basic knowledge in this area often leads to anxiety and the formation of unhealthy habits;
- Preventive consultations – Do not wait for complaints to appear. The first visit to a gynecologist is recommended at the onset of puberty to ensure that physical development corresponds to age-related norms.
According to gynecologist-endocrinologist Nato Shengelia, it is particularly important for parents to overcome sociocultural barriers and foster an open, trusting relationship with their child. Such an environment helps adolescents feel comfortable discussing bodily changes and seeking timely medical advice, which in turn supports early detection of potential issues and access to appropriate care.
